Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976990, here are decompositions:
- 13 + 4294976977 = 4294976990
- 61 + 4294976929 = 4294976990
- 103 + 4294976887 = 4294976990
- 151 + 4294976839 = 4294976990
- 193 + 4294976797 = 4294976990
- 313 + 4294976677 = 4294976990
- 373 + 4294976617 = 4294976990
- 607 + 4294976383 = 4294976990
Showing the first eight; more decompositions exist.
